ABSTRACT:
A vehicle/engine speed data collection and preprocessing method and apparatus comprises obtaining speed signal data, typically from a speed sensor; computing a linear equation of the speed signal data; adding artificial data to the speed signal data in accordance with the linear equation; filtering the speed signal data having the artificial data added thereto; and removing the filtered artificial data from the filtered data. The technique minimizes the transient effects of filtering, particularly at the data boundaries.
